@Nashotah, I'm at about the same level as you. Keep your 200. I haven't skied a Ski Nautique with the 5.3, but have skied a 200 with the 5.3 and found it to have an unforgiving calibration that was quite harsh. I think the 6.0 is better. Regarding the original question in this thread, I think the MasterCraft Prostar slalom wake is the best. I am neutral about the Malibu TXi slalom wake and pull - nothing bad, but nothing special and I have mediocre performances with it. The 200 is a reasonable slalom wake - not as good at 22 off as the Prostar and the 6.0 pull is fine. The Ski Nautique is my least favorite slalom wake of current models (it's still better than the MC 197), but the 6.2 calibration and pull is excellent. I do find the Prostar calibration (6.0) and pull a bit soft and I have to select the plus setting (C2+) to get it close to what I like. I will also say that I liked the 2016 TXi better than the 2017-present model - for both driving and slalom skiing. If I recall correctly, my 34 mph PB is with the Prostar and my 36 mph PB is with the 6.2 Ski Nautique, although it's possible that both were with the Ski Nautique.
